77 * This function accepts a string containing a CSS selector,
78 * basic XPath, or raw HTML, which is then used to match a set of elements.
79 * The HTML string is different from the traditional selectors in that
80 * it creates the DOM elements representing that HTML string, on the fly,
81 * to be (assumedly) inserted into the document later.
83 * The core functionality of jQuery centers around this function.
84 * Everything in jQuery is based upon this, or uses this in some way.
85 * The most basic use of this function is to pass in an expression
86 * (usually consisting of CSS or XPath), which then finds all matching
87 * elements and remembers them for later use.
89 * By default, $() looks for DOM elements within the context of the
90 * current HTML document.
92 * @example $("div > p")
93 * @desc This finds all p elements that are children of a div element.
94 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
95 * @result [ <p>two</p> ]
97 * @example $("<div><p>Hello</p></div>").appendTo("#body")
98 * @desc Creates a div element (and all of its contents) dynamically, and appends it to the element with the ID of body.
101 * @param String expr An expression to search with, or a string of HTML to create on the fly.
107 * This function accepts a string containing a CSS selector, or
108 * basic XPath, which is then used to match a set of elements with the
109 * context of the specified DOM element, or document
111 * @example $("div", xml.responseXML)
112 * @desc This finds all div elements within the specified XML document.
115 * @param String expr An expression to search with.
116 * @param Element context A DOM Element, or Document, representing the base context.
122 * Wrap jQuery functionality around a specific DOM Element.
123 * This function also accepts XML Documents and Window objects
124 * as valid arguments (even though they are not DOM Elements).
126 * @example $(document).find("div > p")
127 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
128 * @result [ <p>two</p> ]
130 * @example $(document.body).background( "black" );
131 * @desc Sets the background color of the page to black.
134 * @param Element elem A DOM element to be encapsulated by a jQuery object.
140 * Wrap jQuery functionality around a set of DOM Elements.
142 * @example $( myForm.elements ).hide()
143 * @desc Hides all the input elements within a form
146 * @param Array<Element> elems An array of DOM elements to be encapsulated by a jQuery object.
152 * A shorthand for $(document).ready(), allowing you to bind a function
153 * to be executed when the DOM document has finished loading. This function
154 * behaves just like $(document).ready(), in that it should be used to wrap
155 * all of the other $() operations on your page. While this function is,
156 * technically, chainable - there really isn't much use for chaining against it.
158 * @example $(function(){
159 * // Document is ready
161 * @desc Executes the function when the DOM is ready to be used.
164 * @param Function fn The function to execute when the DOM is ready.
170 * A means of creating a cloned copy of a jQuery object. This function
171 * copies the set of matched elements from one jQuery object and creates
172 * another, new, jQuery object containing the same elements.
174 * @example var div = $("div");
175 * $( div ).find("p");
176 * @desc Locates all p elements with all div elements, without disrupting the original jQuery object contained in 'div' (as would normally be the case if a simple div.find("p") was done).
179 * @param jQuery obj The jQuery object to be cloned.
184 // Map the jQuery namespace to the '$' one
187 jQuery.fn = jQuery.prototype = {
189 * The current SVN version of jQuery.
200 * The number of elements currently matched.
202 * @example $("img").length;
203 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
206 * @test cmpOK( $("div").length, "==", 2, "Get Number of Elements Found" );
215 * The number of elements currently matched.
217 * @example $("img").size();
218 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
221 * @test cmpOK( $("div").size(), "==", 2, "Get Number of Elements Found" );
232 * Access all matched elements. This serves as a backwards-compatible
233 * way of accessing all matched elements (other than the jQuery object
234 * itself, which is, in fact, an array of elements).
236 * @example $("img").get();
237 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
238 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
240 * @test isSet( $("div").get(), q("main","foo"), "Get All Elements" );
243 * @type Array<Element>
248 * Access a single matched element. num is used to access the
249 * Nth element matched.
251 * @example $("img").get(1);
252 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
253 * @result [ <img src="test1.jpg"/> ]
255 * @test cmpOK( $("div").get(0), "==", document.getElementById("main"), "Get A Single Element" );
259 * @param Number num Access the element in the Nth position.
264 * Set the jQuery object to an array of elements.
266 * @example $("img").get([ document.body ]);
267 * @result $("img").get() == [ document.body ]
272 * @param Elements elems An array of elements
275 get: function( num ) {
276 // Watch for when an array (of elements) is passed in
277 if ( num && num.constructor == Array ) {
279 // Use a tricky hack to make the jQuery object
280 // look and feel like an array
282 [].push.apply( this, num );
286 return num == undefined ?
288 // Return a 'clean' array
289 jQuery.merge( this, [] ) :
291 // Return just the object
296 * Execute a function within the context of every matched element.
297 * This means that every time the passed-in function is executed
298 * (which is once for every element matched) the 'this' keyword
299 * points to the specific element.
301 * Additionally, the function, when executed, is passed a single
302 * argument representing the position of the element in the matched
305 * @example $("img").each(function(){
306 * this.src = "test.jpg";
308 * @before <img/> <img/>
309 * @result <img src="test.jpg"/> <img src="test.jpg"/>
311 * @example $("img").each(function(i){
312 * alert( "Image #" + i + " is " + this );
314 * @before <img/> <img/>
315 * @result <img src="test.jpg"/> <img src="test.jpg"/>
317 * @test var div = $("div");
318 * div.each(function(){this.foo = 'zoo';});
320 * for ( var i = 0; i < div.size(); i++ ) {
321 * if ( div.get(i).foo != "zoo" ) pass = false;
323 * ok( pass, "Execute a function, Relative" );
327 * @param Function fn A function to execute
330 each: function( fn, args ) {
331 return jQuery.each( this, fn, args );
335 * Searches every matched element for the object and returns
336 * the index of the element, if found, starting with zero.
337 * Returns -1 if the object wasn't found.
339 * @example $("*").index(document.getElementById('foobar'))
340 * @before <div id="foobar"></div><b></b><span id="foo"></span>
343 * @example $("*").index(document.getElementById('foo'))
344 * @before <div id="foobar"></div><b></b><span id="foo"></span>

3112 * @before <p>Hello</p><p class="selected">Hello Again</p>
3113 * @result [ <p class="selected">Hello</p>, <p>Hello Again</p> ]
3117 * @param String class A CSS class with which to toggle the elements
3120 toggleClass: function( c ){
3121 jQuery.className[ jQuery.className.has(this,c) ? "remove" : "add" ](this,c);
3125 * Removes all matched elements from the DOM. This does NOT remove them from the
3126 * jQuery object, allowing you to use the matched elements further.
3128 * @example $("p").remove();
3129 * @before <p>Hello</p> how are <p>you?</p>
3134 * @cat DOM/Manipulation
3138 * Removes only elements (out of the list of matched elements) that match
3139 * the specified jQuery expression. This does NOT remove them from the
3140 * jQuery object, allowing you to use the matched elements further.
3142 * @example $("p").remove(".hello");
3143 * @before <p class="hello">Hello</p> how are <p>you?</p>
3144 * @result how are <p>you?</p>
3148 * @param String expr A jQuery expression to filter elements by.
3149 * @cat DOM/Manipulation
3151 remove: function(a){
3152 if ( !a || jQuery.filter( a, [this] ).r )
3153 this.parentNode.removeChild( this );
3157 * Removes all child nodes from the set of matched elements.
3159 * @example $("p").empty()
3160 * @before <p>Hello, <span>Person</span> <a href="#">and person</a></p>
3161 * @result [ <p></p> ]
3165 * @cat DOM/Manipulation
3168 while ( this.firstChild )
3169 this.removeChild( this.firstChild );
3173 * Binds a handler to a particular event (like click) for each matched element.
3174 * The event handler is passed an event object that you can use to prevent
3175 * default behaviour. To stop both default action and event bubbling, your handler
3176 * has to return false.
3178 * @example $("p").bind( "click", function() {
3179 * alert( $(this).text() );
3181 * @before <p>Hello</p>
3182 * @result alert("Hello")
3184 * @example $("form").bind( "submit", function() { return false; } )
3185 * @desc Cancel a default action and prevent it from bubbling by returning false
3186 * from your function.
3188 * @example $("form").bind( "submit", function(event) {
3189 * event.preventDefault();
3191 * @desc Cancel only the default action by using the preventDefault method.
3194 * @example $("form").bind( "submit", function(event) {
3195 * event.stopPropagation();
3197 * @desc Stop only an event from bubbling by using the stopPropagation method.
3201 * @param String type An event type
3202 * @param Function fn A function to bind to the event on each of the set of matched elements
3205 bind: function( type, fn ) {
3206 if ( fn.constructor == String )
3207 fn = new Function("e", ( !fn.indexOf(".") ? "jQuery(this)" : "return " ) + fn);
3208 jQuery.event.add( this, type, fn );
3212 * The opposite of bind, removes a bound event from each of the matched
3213 * elements. You must pass the identical function that was used in the original
3216 * @example $("p").unbind( "click", function() { alert("Hello"); } )
3217 * @before <p onclick="alert('Hello');">Hello</p>
3218 * @result [ <p>Hello</p> ]
3222 * @param String type An event type
3223 * @param Function fn A function to unbind from the event on each of the set of matched elements
3228 * Removes all bound events of a particular type from each of the matched
3231 * @example $("p").unbind( "click" )
3232 * @before <p onclick="alert('Hello');">Hello</p>
3233 * @result [ <p>Hello</p> ]
3237 * @param String type An event type
3242 * Removes all bound events from each of the matched elements.
3244 * @example $("p").unbind()
3245 * @before <p onclick="alert('Hello');">Hello</p>
3246 * @result [ <p>Hello</p> ]
3252 unbind: function( type, fn ) {
3253 jQuery.event.remove( this, type, fn );
3257 * Trigger a type of event on every matched element.
3259 * @example $("p").trigger("click")
3260 * @before <p click="alert('hello')">Hello</p>
3261 * @result alert('hello')
3265 * @param String type An event type to trigger.
3268 trigger: function( type, data ) {
3269 jQuery.event.trigger( type, data, this );
